DeepL Translator now offers both American and British English!

DeepL has now made it easier to get English translations in your preferred style: DeepL Translator can now produce translations that reflect the particularities of American and British English.

Variations in spelling are covered: American neighbors become British neighbours, and they can call each other on their cell phones or on their mobile phones, depending on your preference.

Similarly, terms that have completely different equivalents across the pond are also taken into account. American cookies become British biscuits. That is, of course, unless they’re on your web browser.

This expanded control over DeepL Translator enables you to more quickly get translations that respect the language conventions that you prefer. To set the language variety you would like, simply select either “English (American)” or “English (British)” as the target language.

American and British English are now available as target languages on, via the DeepL API, and in our desktop applications, DeepL for Windows and DeepL for Mac. Combining this feature with other features, such as the Glossary, allows you to take full control of the English texts DeepL Translator produces for you.

*Please note that these two language variants are not currently available for translations from Japanese and Chinese. These two source languages will be added in the near future.

DeepL Pro is now available in Japan.

DeepL Pro - now available in Japan!

Since we added Japanese to DeepL Translator, we’ve been amazed by how quickly people in Japan have taken to using our services. We made it a priority to make our paid subscription service, DeepL Pro, available in Japan and we can now announce that that has become a reality.

All DeepL Pro subscription plans, providing added data protection, unlimited translation capacity, API access, and more, are now available in Japan. Japanese customers also benefit from prices in Yen.

We continue to expand DeepL Pro coverage around the world and will add further countries and currencies in the near future.

Customize DeepL Translator with the Glossary

What’s better than finding the exact right word to express yourself? Always finding the exact right word to express yourself! Our new Glossary feature gives you the power to determine exactly how DeepL Translator should translate terms for you.

Whether you translate legal contracts, technical manuals, or company newsletters, the Glossary can save the terms you use and the translations you like, ensuring consistency and saving you time.

All you need to do is click on a word in the translated text, click on your preferred formulation, and save the Glossary pair when asked. Alternately, you can click on “Customization” and enter it manually.

You can create Glossary entries for nouns, verbs, adjectives, adverbs, and even multi-word entries, and DeepL Translator will adapt the grammar and formulation to accommodate your preferences. You always have the option to turn the Customization feature on or off, giving you full control over how and when the rules you create affect DeepL Translator. Free users of DeepL Translator can create a limited number of Glossary pairs, whereas DeepL Pro subscribers can create as many as they like!

Currently, Glossary pairs can be created for the following language combinations: German into English, French into English, English into German, and English into French. Further language combinations will be added in the near future, as will further options to customize DeepL Translator’s results and make the translations your own.

DeepL Pro is now available in the United States and Canada.

DeepL Pro - now available in the United States and Canada!

We are delighted to announce that DeepL Pro is now available in the Land of the Free and the True North! This has been a longstanding goal of ours and we are very proud to welcome our American and Canadian friends.

All DeepL Pro subscription plans, providing added data protection, unlimited translation capacity, API access, and more, are available immediately. Additionally, we are very happy to allow our North-America-based clients to pay for their DeepL Pro subscriptions in their local currencies, US and Canadian dollars.

We’re constantly working to enter new markets and will be making DeepL Pro available in further countries in the near future.

Please note that while businesses in Quebec may sign up as of today, registration will be open for private citizens shortly.

DeepL Translator now offers a choice of variants of Portuguese.

Brazilian Portuguese now available on DeepL Translator!

Que legal! DeepL Translator is now also capable of translating into Brazilian Portuguese!

The Portuguese language, in all its varieties, is spoken all around the world by millions of people on several continents. The country with the most Lusophones is by far Brazil, with over 200 million people.

To reflect some of this linguistic diversity, our researchers have taught our algorithms to also produce translations in the variety of Portuguese used in Brazil. This allows DeepL Translator to capture the nuances and unique vocabulary of Brazil, as well as the language of millions more in Portugal, Angola, Mozambique, and elsewhere.

Some variations in the Portuguese language are clear to see in the translations of the phrase “The girl is having breakfast.”

Portuguese: A rapariga está a tomar o pequeno-almoço.
Brazilian Portuguese: A menina está tomando o café da manhã.

The terms for “the girl” (a rapariga/a menina) and “breakfast” (o pequeno-almoço/o café da manhã) reflect regional variations, as does the form of the verb tomar; Brazilian Portuguese prefers the gerund, whereas a construction using the infinitive is more common in Portugal and other countries.

The two variations of Portuguese are now available on To select the version you prefer, simply click on the language next to “Translate into” and select either “Portuguese” or “Portuguese (Brazilian).”

Enjoy the many delights of the Portuguese-speaking world!

Japanese and Chinese are now available on DeepL Translator.

DeepL Translator learns Japanese and Chinese

Two of the questions we are most often asked are, “when will you add Japanese?” and “when will you add Chinese?” We are pleased to say, "今日!" Or, "今天!"

The improvements in our neural network architecture that we made early this year have enabled us to achieve translation quality in Japanese and Chinese unlike anything we’ve seen before. To be sure the translations lived up to DeepL’s standards, we once again ran blind tests: We asked Japanese and Chinese translators to evaluate a set of translated texts from various online translation providers, without knowing which site produced which translation. Once again, DeepL’s results were picked as the best more often than any other provider’s, as you can see below:

119 paragraphs from different domains were translated by the various systems. External professional translators were hired to review the translations - without information about which system produced which translation. The graph displays how often each system’s translations were rated better than all other translations. Not shown are cases where several systems produced the best translation. The tests were performed in March 2020.

These two languages and their unique writing systems, posed interesting challenges for our research team. How do you teach a machine to translate to and from languages that are so different from one another? The answer is found in millions of translations, clever mathematics, and invaluable input from our Chinese and Japanese language experts.

The result is an important expansion of DeepL Translator’s capabilities. The algorithms can now handle several thousand Chinese characters, as well as Japanese kanji, hiragana, and katakana. With this vast knowledge, DeepL Translator can now produce translations that use natural-sounding, context-appropriate language in two more of the world’s most-used languages.

This is an important milestone for us; adding Japanese and Chinese expands our language coverage to over a billion potential new users. We are very proud to have been able to respond to the wishes of people around the world and fulfil our ambition to add Japanese and Chinese to DeepL Translator.

January 2020 blind testing once again confirms that DeepL Translator is the world’s best AI translation system.

Another breakthrough in AI translation quality

We are pleased to inform you that, today, we have launched a completely new translation system that represents another quantum leap in translation quality. The neural networks we use are far superior to previous technologies and you can now test and use them free of charge at

We already made some headlines in 2017 when we released DeepL Translator, which was superior in quality to translation systems of even large high-tech companies and was able to translate even longer passages without errors. Our services quickly became popular: they are now used by more than half a billion people.

Now our AI researchers have succeeded in achieving another breakthrough in translation quality. All the criteria that make for a good translation have been improved by the new system. The new neural networks are able to represent the meaning of the translated sentences in the target language much more precisely and, at the same time, are often able to find more professional formulations.

This has prompted us to conduct new blind tests. We translated 119 lengthy passages from a wide variety of subjects using DeepL Translator and some competing systems. We then asked professional translators to evaluate these translations and choose the best translation - without being informed which system produced which translation. The translators selected the translations from DeepL four times more often than those from any other system:

119 paragraphs from different domains were translated by the various systems. External professional translators were hired to review the translations - without information about which system produced which translation. The graph displays how often each system’s translations were rated better than all other translations. Not shown are cases where several systems produced the best translation. The tests were performed in January 2020.

We assume that companies such as Google or Microsoft also have very good data for training neural translation networks. On the other hand, we have achieved many innovations in the mathematics and methodology of neural networks, with the help of which we can extend our lead. It is a special moment for our entire team that these improvements can now be used by billions of people.

At DeepL, our vision is to break down language barriers worldwide and bring cultures closer together. To achieve this, we are planning to add many more languages and, in the coming months and years, we want to integrate translation technology wherever people communicate with each other, read texts, write or do business with each other. This vision also motivates many AI researchers and developers to join DeepL. If you too would like to help us bring the world closer together, please feel free to apply!

DeepL wins first-ever Honorary German AI Award

The night of September 26th was very special for DeepL. In a ceremony at Factory Berlin am Görlitzer Park, DeepL was awarded the first-ever Honorary AI Award at the inaugural German AI Awards (Deutscher KI-Preis). To say that we are honored would be an understatement. Being singled out for this award is an extremely gratifying recognition of our efforts over the past two years.

The German AI Awards were created by Bilanz Magazin with the support of Airbus, BMW Group, Maschmeyer Group, McKinsey & Company, Otto Group, and Presight Capital. In addition to the Honorary Award awarded to DeepL, Dr. Elmar Rückert of the University of Lübeck won the Development Award, and Professor Dr. Kristian Kersting of the “Machine Learning Lab” at the Technical University of Darmstadt took home the Grand Prize.

“We are extremely grateful to Bilanz Magazin and the German AI Awards jury. On behalf of everyone at DeepL, thank you very much!” said DeepL CEO Jaroslaw Kutylowski. “I’d like to congratulate the other award winners and all the nominees, as well. We look forward to seeing the exciting AI developments they are working on.”

The German AI Awards are an excellent initiative to promote and drive innovation in artificial intelligence and show that Germany has incredible potential to be a world leader in this field. We at DeepL are thrilled to be at the forefront of artificial intelligence research worldwide, and to be Germany’s leading AI company.

We view the Honorary AI Award as confirmation that DeepL is a prime example not only of highly-advanced AI technology, but also a meaningful application of that technology that helps millions of people in their everyday lives.

Jaroslaw Kutylowski takes over as DeepL's CEO

We are very excited to announce a new development in the history of DeepL: Co-founder Jaroslaw Kutylowski is our new chief executive officer.

DeepL has established itself as one of the top players in the AI sector with neural network technology capable of a never-before-seen level of textual understanding. Our AI translation services are being used by a rapidly-growing number of corporations, individuals, and professional translators.

In the near future, we will be expanding our range of AI products and services. In order to achieve this, we have doubled our staff in recent months. We are entering an exciting new phase of our development, and Jaroslaw taking over the role of CEO will help us respond to accelerating change.

This move formalizes the key role that Jaroslaw has played in the company for a long time. Since joining the company in 2012 as chief technical officer, Jaroslaw has taken on progressively more responsibilities, not only in expanding our technical capabilities, but also in business operations.

Jaroslaw oversaw the introduction of DeepL Pro, targeting professional users. He was also instrumental in securing the backing of venture capital firm Benchmark in November 2018.

“The most important element for a startup to become successful on a global scale is effective leadership,” explained Benchmark partner Matt Cohler, “the future is very bright for DeepL, and they’ve got the right person at the helm.”

DeepL’s previous CEO, Gereon Frahling, is now able to focus on improving and expanding our AI technology and leading the constantly-growing research team.

“I’m very happy having Jaroslaw officially take the reins as CEO,” said Gereon. “Our team has never been stronger, and I’m very excited about the revolutionary AI ideas we're working on.”

“Jaroslaw knows the company inside out and everyone holds him in the highest regard,” he added, “This is a massive boost for DeepL!”

As for Jaroslaw himself, he’s as excited as everyone else, and has already got down to business: “I’m honoured by the trust that everyone here at DeepL has placed in me and, of course, I’m thrilled. DeepL is already a daily companion for so many people, and we want to continue along the path to becoming one of the world's leading AI companies. Of course, this means that the company needs to grow substantially, and I'm very pleased with the steps we've taken in recent months.”

New languages: Russian and Portuguese!

Bom dia, друзья! You asked, we listened, and today we are extremely excited to give you what you’ve been looking for: Russian and Portuguese translation on DeepL Translator!

By serving these two massive language communities, DeepL can now provide half a billion more people with the world’s best AI translation technology. We are especially pleased that we can add these two major global languages with the same translation quality that has been the hallmark of DeepL since the very beginning.

In blind testing that compared our translations to those of other systems, DeepL’s Russian and Portuguese services consistently emerged as translators’ favorites. These results further confirm that DeepL can compete with, and outperform, established global players.

These definitely won’t be the last languages we add to DeepL Translator: The neural networks are constantly training to master further languages. DeepL remains the world leader in AI translation technology and we continue to have our sights set on further development.

Introducing the DeepL API

Last August, we launched DeepL Translator, a new milestone in machine translation. Since then, hundreds of translators, companies, and developers have approached us with ideas to build great new products on top of this translation technology.

Today, we are introducing the DeepL API, as part of DeepL Pro. Put simply, the DeepL API is an interface that allows other computer programs to send texts to our servers and receive high-quality translations. This opens a whole universe of opportunities for developers worldwide: Any translation product you can imagine can now be built on top of DeepL's superior translation technology. A few examples:

  • Live translation apps: Recently, tech giants and smaller startups alike have announced the development of earbuds that translate in real time, but can only deliver the quality of traditional translation tools. The new DeepL API allows developers to build live translators with DeepL's translation technology, making far fewer mistakes.
  • Augmented reality translations: Point your mobile phone camera at a sign and get the right translation. Such an app could be built by any developer with a DeepL Pro subscription.
  • Operating systems: Translate directly in your browser, chat program, email client, or word processor, as soon as the developers have integrated our technology.
  • Internal communications: Large corporations can integrate our translation technology into their communication systems. They can then get high-quality translations on the fly with our data protection guarantee ensuring the confidentiality of their information.
  • Computer-assisted translation: Leading translation tool provider SDL already allows for the integration of the DeepL API into SDL Trados Suite 2017. Every translator can now benefit from DeepL's incredible neural translations within their favorite translation tool.

Elegantly integrated, high-quality translations will become the new standard. We cannot wait to see the incredible products created by developers who share our vision of a more closely connected world in which language is no longer a barrier.

Data Protection: The EU Advantage

You have probably already seen the incredible difference in quality between DeepL Translator and translation services offered by our competitors. Even better; as a company based in the European Union, DeepL offers you additional benefits when it comes to privacy and confidentiality. Neither source texts, nor their translations, can be obtained by foreign authorities.

EU data protection laws put user protection front and center; we are prohibited from collecting personal data without reason. And, should an EU-based company ever experience a security breach concerning users' data, they are required to inform customers within 72 hours of learning of the incident.

With the new DeepL Pro service, to be launched in March, we will add another layer of data security. We guarantee every DeepL Pro subscriber that we never store the texts they translate. With this guarantee, under European Union law, you can be sure that you and your clients' texts are as secure as possible.

The security of company reports, patents, corporate emails, and customer data is of utmost importance. DeepL guarantees that such documents are treated with the sensitivity and confidentiality that you and your customers deserve.

You care about the privacy of the texts you translate. So do we.

Welcome to the DeepL Blog!

At DeepL, our mission is to bring AI products of the future to everyone, right now. Here in the DeepL Blog, we will keep you updated about our ideas and the innovations that we will bring to the world.

There is currently a lot of hype about AI and what it can possibly achieve in the future. However, real products have yet to fulfill this promise; self-driving car services have yet to appear, personal assistants remain constrained to a small set of queries, and live translators are not yet good enough for smooth conversation.

At DeepL, we are actively launching products that put the future of AI into your hands. We started with DeepL Translator, launched in August 2017. It was described as "outperforming other services" (Le Monde), translating "much more fluently" (Wired), and as having "outdone all the tech giants and raised the bar for the field" (TechCrunch). To achieve our goals, we have been developing a completely new generation of artificial neural networks. Using a novel neural network design, our networks learn to grasp the subtle meanings of sentences, and convey them in the target language in a way not seen before. DeepL Translator is available to everyone, free of charge at

Since our neural networks have developed a previously unseen sense of "understanding", there are numerous more potential applications. You can expect further DeepL products that go way beyond translation and will change the way you handle text and speech. Keep your finger on the pulse here on our blog!
